In detailed scheduling, what is 'infinite loading'?
Answer: Loading work onto work centers without regard to their capacity limits
Infinite loading assigns work to work centers based on priority without checking whether capacity is available, often used to identify overloads for manual resolution.
What is the purpose of 'safety lead time' in a detailed schedule?
Answer: To add buffer time to protect against uncertainty in supply or production
Safety lead time is extra time added to planned lead times as a buffer against variability in processing, transportation, or quality issues.
Which of the following best describes the Theory of Constraints (TOC) approach to scheduling?
Answer: Identify the bottleneck and subordinate all other schedules to it
TOC (Drum-Buffer-Rope) focuses scheduling on the constraint (bottleneck), using it as the 'drum' and subordinating all other resources to ensure the constraint is never starved.
In a pull system using kanban, what triggers the release of a production order?
Answer: A signal (kanban card) from a downstream consuming process
Kanban is a pull system where production at an upstream station is triggered only when a downstream station signals demand, preventing overproduction.
What is 'manufacturing lead time' composed of?
Answer: Queue time, setup time, run time, wait time, and move time
Total manufacturing lead time includes all five elements: queue, setup, run, wait, and move times, with queue time typically being the largest portion.
A planner receives a reschedule-in notice from MRP. What action should be taken?
Answer: Move the planned completion of the order to an earlier date to meet demand sooner
A reschedule-in message means demand moved earlier than the planned order receipt, so the planner should expedite the order to complete it sooner.
Which performance metric best evaluates the effectiveness of a detailed scheduling system?
Answer: On-time completion rate and schedule stability
On-time completion rate measures whether the schedule achieves its due-date targets, and schedule stability measures how frequently the plan must be revised, both key scheduling effectiveness indicators.
